Please, there now has to be someone who can get this working!

[Me Myself and I]

I'm having trouble getting
  
gcc-java-4.6.2.tar
  
working under windows 7 mingw32. I have read the instructions with that download,
and find that key scripts just don't want to work.  I have also become aware
of the instructions at
 
http://rmathew.com/articles/gcj/bldgcj.html
 
which claims that gcj inside windows can be done
 
 
-Is there a simple set of commands I can use to get my compiler download
built and working?
 
Can someone please help?
